DOUBLE-LIFT JACQUARD-MAGHINE.

Toall whom it may concern:

Be it known that I, ERNST HANme, a subjeet of the Emperor of Germany,residing at town of Union, in the county of Hudson and State of NewJersey, have invented certam new and useful Improvements in Double-LiftJacquard-Machines, of WlllCh the following is a specificatlon.

This invention relates to double-11ft acquard machines, 1;. e1, jacquardmachines 1n which each harness cord is controlled by two hooks which solong as the end or warp thread to which they apperta1n, remalns called,reciprocate in opposite dlrections, holding the end raised until it 1sto be depressed for one Or more picks 1n the fabric. The meansconnecting each harness cord with its two hooks is usually a cordcoupling whose upper end portion is forked so as to be attached to thetwo hooks and whose lower end carries a hook or the like to Which theharness cord is attached. The cord couplings-termed colletsbesides beingsubject to wear and therefore requiring constant attention, becometwlsted and due to i this and to one branch of each collet necessarilykinking in slackening when the other is up, serious interference wlththe necessary perfect freedom of up and down movement of the liftingunits prevails; moreover, by twisting and also by stretching, thecollets change in length so that the alinement of the ends is disturbedand hence the harnesses cannot be used interchangeably.

The principal object ofthis invention is to provide a coupling meansbetween each pair of complementary hooks and the corresponding harnesscord whereby all these objections will be overcome, and thisI accomplish by a novel form ofcoupling device of a stiff upright memberhaving means for attachment thereto of equivalent, and a pair ofcouplings freely slidable up and down on the hooked lower.

portions of said hooks.

In the accompanying drawing, Figure 1 shows a jacquard machine invertical section provided with the improved coupling means;

Preferably the im roved coupling means comprises two mem ers, uppermember A and lower member B.

Upper member A is preferably composed of wire, thus being stiff bent toform upright portions or mem ers e of suitable length, laterally bentends f on said portlons, a transverse connection 9 bet-Ween said ends,and eyes h (closed in the adaptation illustrated) at the lower endsofsaid portions, standing side by side. Connection 9 is of a length atrifle exceeding the spacing of the adjoining upright porti0ns d d ofhooks d, wherefore, since eyes it are close together, members 6 econverge downwardly.

Member B is a straight length of wire 2' having its ends formed as eyes7' is (or equivalent) for coupling, as shown, with the eyes forattachment of .the harness cord Z.

Each coupling device so formed has the bent-off end portions f-of itsmembers e penetrating one of the two complementary hooks d d, so thatthe device hangs pendent, the coupling it affords at one such part wherea laterally bent end 7 occurs'being adapted to move up and down with onehook while the other such coupling is perfectly free to slide on thepart d of the other hook, the device as a whole being kept topractically a of action at all times.

The construction being such, as explained, that when one of acomplementary pair of hooks rises and falls the up and down motion ofthe coupling device occurs with perfect freedom with respect to theother hook and without shifting out of its normal vertical plane; nointerference of any character can occur and the alinement of the ends,once efiected, remains absolutely con- ,Further, no undue space beingrequired in' respect to the form or manner of operation of the device, agreater number lifting units can be employed than is usual indouble-lift jacquard machines.

3. In combination, with the depending hooked portions of a complementarypair of 40 hooks of a double-lift jacquard machine, a harness cordcoupling device including a pair of stifi' upright portions having theirupper ends bent laterally and penetrating said hooked portions, atransverse rigid connection between said ends and side-by-side eyes atthe lower ends of said portions arranged in a plane oblique to thevertical plane of said transverse portion.

In testimony whereof I aflix my signature.
